U S Divers Proflex II Diving Fins

U.S. Divers offers a variety of fin styles to meet the needs of water sports enthusiasts whether they’re diving, snorkeling, tube fishing, body surfing, or having fun in the pool, and the Twinflex scuba fin is among the best. The Twinflex is distinguished by its dual blade channels, which optimize the water flow and enhance the thrust of the diver. Users will also appreciate the TPR center flex zones, which cup the water efficiently to provide greater underwater power. The fins fit a variety of foot sizes and shapes with ease. U.S. Divers recommends wearing dive boots with the Twinflex fins, which come in M (6 to 9), L (9 to 11), and XL (11 to 13) sizes. The Twinflex is also backed by a two-year limited warranty.
User Ratings and Reviews
5 Stars Something to consider……….
I bought these fins, and was impressed when I inspected them out of the box. But I can’t use them. I have size 9 1/2 EEE feet (mens) and the fins are too tight. Just trying them on at home for a few minutes was killing the top of my foot. I ordered size L 9 1/2 to 11 1/2. I didn’t exchange them for the next size up, I think they would be way too big, and fly off my feet when swimming. Instead I returned them and bought fins with an adjustable strap. It’s too bad, because these look to be decent quality for the price. My advice would be if you have “normal” feet, buy them. But if you have a wide foot, I would recommend you go to a dive shop, gets fins with straps, or at very least buy the fins from someplace with a great return policy.
5 Stars Couldn’t have been happier
I ordered these fins at the last moment for a SCUBA trip to Playa del Carmen/Cozumel as they were smaller than my normal fins and I didn’t have to pack my boots. These worked great for drift diving and I lucked out as the fit was very good (went to the U.S. Divers website for chart). I also ordered neoprene “socks” which made them even more comfortable. They are quite a bit more flexible than my regular fins so I probably wouldn’t use them if I had to swim against a really strong current. Would definitely recommend them as well as the prompt shipping from the company; they arrived a couple of days earlier than what was provided in the shipping information. Very happy with the overall product.
5 Stars Awesome fins!
My son bought these fins and loves them. They fit well and don’t come off in the water or on the land. The downside is that they are not adjustable and therefore won’t be around as he grows out of them. The upside is that you can swim really fast without tiring.
5 Stars comfort and performance
Even in some pretty strong currents in the Belize reefs, these fins imbued confidence. When choosing a size, go to the US Divers web site and see the size chart–it is for men only. Then Google a men-to-women shoe size conversion chart if you’re female. We did this for 6 family members and it worked like a charm. Very comfy fins.
3 Stars TOO BIG!
I normally wear a size 6, so I ordered the size Small (5-6.5) – and they were too big!!! I wish I had ordered from the kid’s sizes or if they had an XS instead. While snorkeling in the ocean, one of them came off my foot – NOT cool!!! The nice thing was that it sorta floated around and then came close to the surface, so I didn’t lose it. Had they fit, I think I would’ve given a higher rating and would’ve liked them for the purpose of snorkeling expeditions. Unfortunately, I am super bummed about this purchase.
